A hypergraph ℋ is a sum hypergraph iff there are a finite S ⊆ ℕ⁺ and d̲,d̅ ∈ ℕ⁺ with 1 d̲ d̅ such that ℋ is isomorphic to the hypergraph ℋ_d̲,d̅(S) = (V,) where V = S and = e ⊆ S: d̲ |e| d̅ ∧ ∑_v∈ e v∈ S. For an arbitrary hypergraph ℋ the sum number(ℋ ) is defined to be the minimum number of isolatedvertices w₁,..., w_σ∉ V such that ℋ ∪ w₁,..., w_σ is a sum hypergraph.
Keywords: hypergraphs, sum number, vertex labelling
